There are many methods to pre-exhaust. Such as possibly completing flyes first (normal weight-does not have to be high reps) and then doing your pressing second. Hoping at this point the target muscle actually fatigues first, prior to the ancillaries. Or warm up on both your isolation and primary then launch into supersets: eg: isolation immediately followed by compound without resting. Rest & repeat.
Done correctly and with full weight and intensity you will soon know if it targets the muscle in question effectively. Problem is, most people hold back on their isolation exercise knowing their primary is next. That = failure.
